Pass the Paloalto Networks Network Security Administrator NGFW-Engineer Questions and answers with CertsForce

When configuring a new security zone on a Palo Alto Networks firewall, the two valid zone types are:

Tunnel: A Tunnel zone is used for traffic that is associated with a VPN tunnel, such as IPSec tunnels. Traffic passing through a tunnel interface is classified into this zone.

Virtual Wire: A Virtual Wire zone is used when a firewall operates in transparent mode (also known as Layer 2 mode). In this configuration, the firewall can inspect traffic without modifying the IP address structure of the network.

In this scenario, the customer requires that users do not directly access websites and that a security device (the firewall) manages the connection, while also ensuring that there is authentication back to the Active Directory (AD) servers for all sessions. The explicit proxy with Kerberos authentication is the best solution because:

The explicit proxy allows the firewall to intercept user web traffic and manage the connections on behalf of users.

Kerberos authentication ensures that the user’s identity is validated against the Active Directory servers before the session is allowed, fulfilling the authentication requirement.

When the preemptive hold time is set to 0 minutes in route monitoring, the firewall is configured to immediately reinstall the route into the Routing Information Base (RIB) as soon as the monitored path comes up. This essentially means that the firewall will not wait for any predefined hold time before reestablishing the route once the monitoring condition is met, ensuring a faster recovery of the route.

Assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW is used to define granular permissions for management tasks. This allows administrators to control what actions a user can perform on the firewall, such as configuration changes, monitoring, and logging. By assigning different admin roles, you can ensure that users have access only to the areas and tasks they need, enforcing the principle of least privilege.

When building a custom report on a Palo Alto Networks NGFW, you can select detailed logs that provide specific insights into various aspects of firewall activity. The available options for detailed logs typically include:

Traffic logs: These provide information on the network traffic passing through the firewall.

Threat logs: These logs capture data related to identified security threats, such as malware or intrusion attempts.

Data filtering logs: These logs capture events related to data filtering policies, such as preventing the transfer of sensitive data.

User-ID logs: These logs associate user identities with the traffic and activities observed on the firewall, enabling user-based policy enforcement.
